• Integrated Smart BESS — 261kWh LFP battery with liquid cooling, EMS, and fire suppression • Multi-Use Energy Storage — Built for renewables, EV charging, backup power, and peak load management • Safe & Scalable — Real-time monitoring, remote diagnostics, and globally certified architecture HYDERABAD, India, June 8, 2026 /PRNewswire/ -- Trex Energy, an innovative energy storage solutions company headquartered in Hyderabad, Telangana, today announced the official commercial launch of the REX BESS 125kW/261kWh with Liquid-Cooling Battery Energy Storage System (BESS). The REX BESS from Trex Energy combines liquid cooling, intelligent energy management system, and integrated AC/DC architecture to deliver reliable, scalable energy storage for commercial, industrial, and utility applications in India and globally. This product launch arrives against the backdrop of MSEDCL's new tariff policy, which signals electricity tariff rebates for the adoption of energy storage solutions Product Overview: The REX BESS 125kW/261kWh BESS The REX BESS is a fully integrated, single-cabinet energy storage solution featuring a 261 kWh LFP (Lithium Iron Phosphate) battery with a nominal voltage of 832V and a cell capacity of 314Ah. With a maximum DC voltage of 950V and a maximum input active power of 125kW, the system is designed for high-efficiency charge-discharge cycles across both on-grid and off-grid configurations. Operating reliably across temperatures from -20°C to 55°C, and rated IP54 for protection against dust and water ingress, the REX BESS is built for real-world industrial conditions. Commenting on the launch Roshan Shaik, Technical Director - Trex Energy, said, "The REX BESS is not just a product — it is our commitment to India's energy future. With liquid cooling, aerosol fire suppression, and intelligent cloud monitoring built into a single cabinet, we are giving our customers a system they can trust for decades of reliable operation." Key Features Efficient & Scalable: Flexible expansion design allows one machine to serve multi-effect matching across a variety of application scenarios. Optional 100kW MPPT and 200kW STS support future capacity growth without system replacement. Reliable & Safe: Equipped with aerosol fire suppression and multiple protection systems covering overcharge, over-discharge, short circuit, and thermal events — ensuring safety across all operating conditions. Smart Energy Intelligence: Integrated Energy Management System (EMS) with 4G connectivity and a 7-inch HMI touch screen enables real-time monitoring, remote diagnostics, and fingertip cloud maintenance from anywhere. Fully Integrated System: Highly integrated AC and DC design in a single cabinet (under 1700×1350×2200mm, under 3500kg). Compatible with PV input, AC bus, grid, loads, and EV charging piles in a unified architecture. Advanced Liquid Cooling: Precision liquid cooling maintains optimal cell temperatures across all conditions, significantly reducing degradation and extending the battery lifecycle compared to conventional air-cooled systems. Applications The REX BESS 125kW/261kWh BESS is designed to address a wide spectrum of energy challenges across industries: Peak Load Management: Reduce electricity costs significantly through effective peak shaving and load shifting, lowering demand charges for commercial and industrial facilities. Renewable Integration: Enhance solar (PV) and wind energy utilization with stable, high-capacity storage — directly compatible with PV input through the integrated EMS architecture. Energy Backup: Provide reliable power supply during grid outages for uninterrupted operations in critical facilities, manufacturing units, and data centers. EV Charging Support: Enable efficient and scalable EV charging infrastructure with stable power delivery, supporting India's fast-growing electric mobility ecosystem. Grid Support: Strengthen power networks with distributed energy solutions — supporting frequency regulation, voltage stabilization, and load balancing for utilities. Energy Trading (Arbitrage): Maximize savings by leveraging energy price fluctuations — charging during off-peak hours and discharging during peak tariff periods.
